• Corythucha ciliata

  sycamore lace bug, plane lace bug, Eastern Sycamore Lace Bug

  Corythucha ciliata, the sycamore lace bug, is a small sap-sucking insect native to North America that has become a globally invasive pest of plane trees (Platanus spp.). Adults are milky white, 3.2–3.7 mm long, with distinctive lacy, reticulate wings. The species was first detected in Europe in 1964 in Italy and has since spread to over three dozen countries across Europe, Asia, and Oceania. It feeds exclusively on the undersides of leaves, causing chlorotic stippling, premature leaf drop, and tree weakening. In Europe, it has been reported to bite humans and cause dermatological reactions.

• Phyllonorycter platani

  London Midget, plane leaf miner

  Phyllonorycter platani is a small leaf-mining moth in the family Gracillariidae, commonly known as the London Midget or plane leaf miner. The species is notable for its association with Platanus (plane trees) as its larval host, creating distinctive blotch mines on leaves. It has been introduced to North America and is considered an invasive species in some regions. The moth has a wingspan of 8–10 mm and produces two generations annually in parts of its range.
